Ah, good idea on supplying the analog guage too!
Another thought on pinging at 1.9... the idle mixture should be
checked, NOW. Since the computer goes open loop at boost or WOT,
if the idle mixture is incorrect, this can actually lean rather
than richen the mixture.
On the 5kTs, I think the recommended duty cycle for the O2 frequency
valve is 40% or 38 degrees (this is for best power).
